AI identifies a $14bn solar problem

How do you know when an inverter or module is under-performing? Monitoring services should shed light on problems but AI-driven digital asset manager Raycatch says much information is hidden behind a wall of “noise.” Breaking that wall with advanced data analysis could unlock billions of cost savings.

Mitsui Chemicals’ Gujarat lab now BIS-recognized for solar panel testing 

The Japanese firm, which established the lab in association with Germany-headquartered technical advisor PI Berlin, eventually plans to set up a diagnostic business for solar panels and power plants in India.

Waaree’s solar module testing lab becomes NABL accredited

The lab—located at Waaree’s factory in Gujarat—is the first such by an Indian module manufacturer and can perform more than 30 critical IEC tests.

Conformity assessment of solar PV panels in India

Quality of testing is equally important even as new test labs come up for solar modules. Proper equipment selection and frequent calibration of equipment are prerequisites to ensure the credibility of the test results.

The long read: More or less

How much granularity in monitoring and optimization is enough? Module-level power electronics have been a popular addition to the residential segment and, for several reasons, have enjoyed growing popularity on commercial rooftops. But where is the limit? While there are the first ground-mount installations with MLPE, other companies suggest that less is more and scaled down their optimization and monitoring granularity.

The long read: The right tools and tenders for building a quality framework in India

“Quality control is expensive.” This common misperception is largely responsible for many of the product defects, design mistakes, and bad practices in the construction and commissioning of PV plants in several markets around the world. Strong downward price pressure underlined by reverse-auctions has created a false assumption that a budget for quality control is not necessary – as PI Berlin’s work in India is revealing.
